2025 Serica 5303 Diving Chronometer Porcelain White 39mm

Here we have a 2025 Serica 5303 Diving Chronometer Porcelain White with a 39mm polished and satin-brushed stainless steel case. A lug-to-lug length of 46mm and a thickness of 12mm ensure a comfortable fit on your wrist. The case features twisted lyre-style lugs drilled for easy strap changing, and an oversized screw-down crown sits on the right side. The distinctive dual-scale unidirectional bezel consists of an outer ring made from engraved polished white high-density ceramic featuring a 60-minute dive scale, paired with an inner brushed stainless steel ring displaying a 12-hour dual-time scale. A double-domed sapphire crystal protects the striking, glossy porcelain white dial. The dial features printed hour plots placed closer to the centre, creating an unconventional layout with painted indices coated in SuperLumiNova C3. The stylised broad arrow hour hand and sword minute hand are coated in the same luminance, complemented by a sweeping second hand with a circular counterweight. On the reverse, a screw-down case back with the serial number engraved. Inside is an automatic Soprod Cal. M100, 25 jewels, 28,800 beats per hour, the chronometer-certified (COSC) in-house regulated movement features hand winding and hacking for your convenience.

The first thing that struck me when I put this on was the contrast. The bright porcelain white dial against the polished black ceramic and brushed steel bezel creates a look that's incredibly crisp. It's bold without being loud and has a real presence on the wrist. Serica has also done a fantastic job of keeping the design clean and purposeful. Every element feels considered, and the unconventional dial layout gives the watch a distinctive identity while remaining wonderfully legible. It's one of those watches that keeps drawing your eye throughout the day. The interplay between the bright dial, contrasting bezel, and polished surfaces makes for a genuinely striking wearing experience, and it's a brilliant reminder that dive watches don't always have to follow the same well-trodden formula. Add this great watch to your collection today!

Serica has been set up by four friends, including Matt Hranek, author of A Man & His Watch, and founder of the WM Brown Project blog. Created in the latter part of 2019. The four decided to create a modern watch designed inspired by the famous Dirty Dozen “W.W.W.” "Wrist Watch Waterproof" design that satisfies a need in the market for a modern, resistant and affordable watch that retains a genuine elegance.
